DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a plasma display panel and a method for manufacturing the same.

[0002]

2. Description of the Related Art In an AC plasma display panel, improvement of luminance and luminous efficiency, that is, reduction of power consumption are important issues. Generally, in a plasma display panel, a pair of surface discharge electrodes (transparent) on a display surface side substrate is used. The discharge generated between the electrodes spreads over the electrodes due to the electric field and spreads outside the electrodes for a free path until the charge disappears. Therefore, in order to prevent erroneous discharge between display light-emitting units (cells), cells are divided. The gap between the non-discharge gaps must be made sufficiently large, and the non-light emitting area becomes large, resulting in a decrease in luminance.

In addition, since an auxiliary electrode called a bus electrode is generally formed of a metal film and does not transmit light, discharge in a portion overlapping the bus electrode hardly contributes to light emission. On the other hand, in the direction orthogonal to the surface discharge electrodes, there is a partition that spatially isolates the display cell, and although the discharge spreads to this partition, it is known that the discharge near the partition does not contribute to the luminance for the power consumption. ing. This is thought to be due to the disappearance of the electric charge on the partition wall surface, but it causes a decrease in power-luminous efficiency.

[0004] In general, there is a trade-off between improvement in luminance and suppression of power consumption, but a method for improving efficiency without decreasing luminance has been proposed. For example, JP-A-8
JP-77292, JP-A-8-77930 and the like disclose a method (first conventional method) in which all insulating layers have a low dielectric constant in order to suppress power consumption.
Japanese Patent Laying-Open No. 4-218238 discloses a method (second conventional method) in which the dielectric constant between display segments is reduced to reduce the power consumption in that portion.

Japanese Patent Application Laid-Open No. Hei 8-250029 discloses a method of partially increasing the thickness of an insulating layer (third conventional method). In order to prevent erroneous discharge (abnormal discharge) between cells, a method is disclosed in which a recess is formed in a discharge portion and a material having a high dielectric constant is embedded therein (fourth conventional method).

[0006]

However, the above-mentioned conventional method has the following problems. First, in the first conventional method for lowering the dielectric constant of all the insulating layers and in the second conventional method for lowering the dielectric constant between display segments,
Although the power consumption of the entire device can be reduced,
Since the fine structure in one light emitting cell is not taken into consideration at all, there is a problem that improvement in luminance cannot be obtained. In the third conventional method in which the thickness of the insulating layer is partially increased, partial discharge can be suppressed in principle. However, in order to obtain the effect sufficiently, the film thickness is usually reduced. However, there is a disadvantage that the surface is not smooth and it is difficult to maintain the adhesion to the partition walls.

[0007] Further, in any of the first to fourth conventional methods, there is no knowledge about the reduction in efficiency due to charge disappearance in the vicinity of the partition, and only the adhesion to the dielectric at the portion in contact with the partition is considered. The patterning of the dielectric is performed by screen printing and etching.
This method is not a practical processing method for the fine structure of the light emitting cell. That is, it is known that formation of such a fine structure is very difficult in screen printing due to the limit of printing accuracy, and in etching, it is chemically insoluble at a relatively low temperature used in a plasma display panel. There is a problem in stability as a processing method of a stable dielectric glass.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and a main object of the present invention is to provide a plasma display panel capable of suppressing power consumption and increasing luminous efficiency per unit cell, and a method of manufacturing the same.

[0010] In a second aspect, the present invention provides a method for manufacturing a plasma display panel.

[0012]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an embodiment of the present invention;

First Embodiment First, a plasma display panel according to a first embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a diagram schematically showing the structure of a plasma display panel according to the present embodiment, which shows a top view and a cross-sectional view taken along line AA ′ and line BB ′ in the top view. FIGS. 2A and 2B are diagrams showing the effects of the plasma display panel of the present embodiment. FIG. 2A shows the conventional plasma display panel, and FIG. 2B shows the plasma display panel of the present embodiment.

As shown in FIG. 1, the plasma display panel includes a display surface side substrate and a back side substrate, and the display surface side substrate includes a transparent electrode 7 serving as a row electrode, a bus electrode 6 and these. A substantially transparent insulating layer for covering is formed, and a column electrode 4, partition walls 3 for separating cells, and phosphors 2 for performing discharge are formed on the rear substrate. Here, in the plasma display panel of this embodiment, the substantially transparent insulating layer of the display surface side substrate is composed of a dielectric having a low dielectric constant and a dielectric 8 having a high dielectric constant, and these are arranged in a predetermined region. It is characterized by:

Next, a method of manufacturing the plasma display panel of the present embodiment will be described. First, on the display surface side substrate, a transparent electrode 7 to be a row electrode row for surface discharge is formed on a glass substrate by sputtering or vapor deposition of tin oxide / ITO, and a silver paste is printed on the transparent electrode 7.・
By firing, a so-called bus electrode 6 is formed. And then
After a substantially transparent insulating layer covering these is formed by printing and baking, MgO is formed as a protective layer by a sputtering method to form a display surface side substrate.

The method of forming the insulating layer on the display surface side substrate will be described in detail. First, a photosensitive paste formed by kneading a glass powder having a low dielectric constant and a photosensitive resin is uniformly applied to the substrate and dried. Then, the coating film is exposed to ultraviolet rays for curing the resin using a mask having a desired pattern, and then developed with an aqueous solution of sodium carbonate to remove unexposed portions. Next, a paste having a high dielectric constant was applied to the removed portion with a rubber squeegee and then dried, and a portion sinking by drying was applied again to form a substantially uniform film thickness. Then, this coating film was fired at a temperature equal to or higher than the softening point of glass to obtain an insulating film having a uniform film thickness but having a partially different dielectric constant.

In addition to the above-described manufacturing method, this insulating layer may be formed by first forming a portion having a high dielectric constant with a photosensitive paste and embedding a paste of a glass having a low dielectric constant. A method in which a film is formed on a substrate in an inverted pattern, and a glass paste is applied to the grooves, and instead of embedding the next dielectric paste in the grooves between the first formed dielectric patterns, a second paste is applied to the entire surface. It can also be formed by applying a method such as a method of applying a paste and then polishing the surface as necessary to remove a thickened portion to improve smoothness.

Next, a method of forming the rear substrate will be described. A silver paste is printed on a glass substrate to form column electrodes 4 and the column electrodes 4 are separated by a height of about 100 μm. The partition walls 3 are formed by a printing method or a sandblasting method, and the phosphor 2 is embedded between the partition walls 3 by screen printing or the like to form a rear substrate. Then, the display surface side substrate and the rear side substrate are faced so that the row electrodes and the column electrodes are perpendicular to each other and the structures are in contact with each other. A plasma display panel was prepared by substituting a suitable gas such as He, Ne, or Xe.

Looking at the distribution in the light emitting cells of the AC plasma display panel, as shown in FIG. 2 (a), the discharge near the partition which spatially isolates the display cells contributes to the luminance for the power consumption. It is known not to. On the other hand, in the present embodiment, as shown in FIG. 2B, a low dielectric constant dielectric having a low dielectric constant is arranged in the vicinity of the partition wall, which little contributes to the display light emission, and an extra discharge is generated. By making it less likely to occur, the discharge efficiency is increased only in the areas where discharge / emission is required, thus reducing power consumption and
The luminous efficiency of the panel can be increased.

Further, it has been difficult to form such a fine structure by a conventional manufacturing method. However, a photosensitive paste obtained by combining photolithography and a thick film technique (a photosensitive dielectric paste is applied, dried and exposed)・ Development of plasma display panels with high yield by applying the technology of “development and baking” or the lift-off method (lamination of dry film, exposure, development, application of dielectric paste, drying, DFR peeling and baking) Is possible.

Embodiment 2 Next, a plasma display panel according to a second embodiment of the present invention will be described with reference to FIG. FIG. 3 schematically shows the structure of the plasma display panel of the second embodiment, and shows a top view and a cross-sectional view taken along line AA 'and line BB' of the top view. .

As shown in FIG. 3, the feature of the plasma display panel of the present embodiment is that a substantially transparent insulating layer covering the transparent electrodes 7 and the bus electrodes 6 serving as the row electrodes of the display surface side substrate is formed with a low dielectric constant and a low dielectric constant. It is composed of a dielectric constant dielectric material 9 and a high dielectric constant dielectric material 8 having a high dielectric constant, and the low dielectric constant dielectric material 9 is disposed along the direction of the transparent electrode. This is the same as in the first embodiment.

A method of manufacturing a plasma display panel having such a structure will be described. First, on the display surface side substrate, a surface discharge transparent electrode 7 made of tin oxide, ITO, or the like is formed on a glass substrate, and the transparent electrode 7 is formed. A bus electrode 6 made of silver paste or the like is formed on the electrode 7. Next, a low dielectric constant dielectric 9 made of a glass powder having a low dielectric constant and a photosensitive paste is formed by patterning. In this embodiment, only a portion of the adjacent cell covered with the bus electrode 6 has a low dielectric constant. The dielectric 9 is formed so as to remain. Thereafter, a paste having a high dielectric constant is applied to the unformed portion to form an insulating layer having a substantially uniform thickness, and MgO is formed thereon as a protective layer to manufacture a display surface side substrate.

As a method for producing a transparent insulating film, a portion having a high dielectric constant is first formed with a photosensitive paste and a glass paste having a low dielectric constant is embedded, or a dry film is formed without using a photosensitive paste. A method of forming on a substrate with an inverted pattern and applying glass paste to the groove portion,
Instead of embedding the next dielectric paste in the grooves between the first formed dielectric patterns, apply the second paste over the entire surface and then polish the surface as necessary to remove the thickened portions and smooth out The method for improving the performance is the same as in the first embodiment.

Next, a silver paste is printed on a glass substrate to form column electrodes 4, and a partition having a height of about 100 μm is formed so as to separate the column electrodes 4 one by one. A phosphor is buried between the substrates by screen printing or the like to form a rear substrate. Then, the display surface side substrate and the back side substrate were faced so that the row electrodes and the column electrodes were perpendicular to each other and the structures were in contact with each other, and the gas in the discharge space was replaced to produce a plasma display panel.

In this embodiment, as in the first embodiment described above, the low dielectric constant dielectric material 9 having a low dielectric constant is disposed in a portion where the contribution to the display light emission is small. By efficiently discharging and emitting light only in the portion indicated as, power consumption can be suppressed, and the luminous efficiency of the panel can be increased.

In the structure of the present embodiment, the low-dielectric-constant dielectric 9 is disposed in the non-display portion (non-discharge gap) between the light-emitting cells, so that a cell that has discharged is adjacent to a cell that has not discharged. This can suppress the phenomenon of erroneous discharge (flicker) due to the spread of the discharge. By utilizing the effect of suppressing the erroneous discharge, a design can be made in which the non-discharge gap is narrowed, so that the area used for display light emission can be increased, and the luminance can be improved.

Third Embodiment Next, a plasma display panel according to a third embodiment of the present invention will be described with reference to FIG. FIG. 4 schematically shows the structure of the plasma display panel of the third embodiment, and shows a top view and a cross-sectional view taken along line AA ′ and line BB ′ of the top view. .

As shown in FIG. 4, in the plasma display panel of the present embodiment, the low dielectric constant dielectric 9 covering the transparent electrode 7 serving as a row electrode and the bus electrode 6 on the display surface side substrate is used as the first dielectric material. It is characterized in that each of the low dielectric constant dielectrics 9 of the embodiment and the second embodiment is an overlapping region. That is, since the low dielectric constant dielectric 9 is formed so as to remain only in the region near the partition wall 3 or in the portion of the adjacent cell covered with the bus electrode 6, the bus electrode 6 formed of a metal film is formed.
By suppressing excess discharge in the vicinity of the partition wall 3 and efficiently discharging and emitting light only in a portion where discharge and emission are required, power consumption can be suppressed and the luminous efficiency of the panel can be increased.

Further, similarly to the above-described second embodiment, the phenomenon of erroneous discharge (flicker) in a non-display portion (non-discharge gap) between light emitting cells can be suppressed. By utilizing the effect of suppressing the erroneous discharge, a design can be made in which the non-discharge gap is narrowed, so that the area used for display light emission can be increased, and the luminance can be improved.

Embodiment 4 Next, a plasma display panel according to a fourth embodiment of the present invention will be described with reference to FIGS. FIGS. 5 and 6 schematically show the structure of a plasma display panel according to the fourth embodiment. FIG. 5A is a top view and FIG.
A cross-sectional view taken along line B 'is shown.

As shown in FIGS. 5 and 6, the plasma display panel of this embodiment has a laminated structure in which an insulating layer covering the transparent electrode 7 and the bus electrode 6 on the display surface side substrate has a laminated structure, and the bus electrode 6 of an adjacent cell. The low dielectric constant dielectric 9 is provided only in the portion covered with the barrier ribs or in the region near the partition 3 on the partition 3 side (see FIG. 5), or only in the transparent electrode 7 and the bus electrode 6 side. A low dielectric constant dielectric 9 is provided (see FIG. 6).

As described above, by disposing a low dielectric constant dielectric in a part of the laminated insulating layers, an excessive discharge in the vicinity of the bus electrode and the partition wall formed of the metal film can be suppressed. Efficiently discharges and emits light only in areas where discharge and light emission are required, thereby reducing power consumption and increasing the luminous efficiency of the panel, preventing erroneous discharge in non-display areas between light emitting cells. can do.

[0034]

As described above, according to the structure of the present embodiment, a low dielectric constant dielectric having a low dielectric constant is arranged in the vicinity of the partition wall which contributes little to display light emission, so that extra discharge is unlikely to occur. However, by preventing the current from flowing, it is possible to efficiently discharge and emit light only in a portion that requires discharge and light emission, thereby suppressing power consumption and increasing the light emission efficiency of the panel.

If a low dielectric constant dielectric is disposed in a non-display portion (non-discharge gap) between the light emitting cells, an erroneous discharge due to the spread of the discharge from a discharging cell to an adjacent non-discharging cell ( The phenomenon that causes flickering can be suppressed, and the effect of suppressing erroneous discharge can be used to design the non-discharge gap to be narrowed, so that the area used for display light emission can be increased. Thus, there is an effect that the display quality can be improved.
